5 of 5 All You Require Is A USB Socket!!! August 6, 2022
Reviewer: Michel J. Gaudet from Adams, MA United States  
I am EXTREMLY pleased with my purchase of the two units I bought.  I LOVE that I do not need to 'find' an un-used electrical socket to plug into.  I have USB sockets almost everywhere throughout the home, so that is a HUGE plus for these two bettery chargers.

The best thing, regarding the device, is how EASY it now is for me to see batteries needing to be replaced.  I have other 'chargers' that will allow this, but only by knowing how to GET to the resistance feature.  The "NITECORE" device AUTOMATICALLY SHOWS YOU THE VALUES!!!  I don't have to remember special key presses and such.  YAY!!!

I bought TWO of the devices, but if this-here "Old-fart", what's in his 70s, starts getting geared back up again towards needing to have heaps of charged batteries 'at the ready', so-to-speak, I just may end-up getting a few more!!!

OH!  I just remembered.  Pulling the connectors to fit in batteries?  SILKY SMOOTH with NO binding.  THANKS, "NITECORE"!
